Original application filed May 29, l9;., Serial No. 564,322. DividSerial No. 556,353.

F0 all whom it may concern:

Be it known that l, Josnrn illloss,'a citi zen of the United States,residing at lVoonsocket, in the county oi Providel'ice, ii-tote oflihode Island, have invented certain new and useful Improvement inCottonlreparing Machines and the like, of which the following is aspecification, reference being had therein to the accompanying urawings.

The present invention is a division of the generic invention upon whichis based my application for U. S. Letters Patent tiled .39, 1922, SerialNo. 564,322. it is appli cable to machines used in preparing cotton andoils 'ibrous materials for spinning and especiall to openers andmachines associated .vit-h the latter nnd opera to supply cot ton, orthe like, thereto. A particular association or assemblage machineshaving the cooperative relationshi p just indicated is that of aso-called hale-breaker and an opener. the case of this association orassemblw'e of machines, cotton in a more or less compressed state,'lfreipieotly in thick shoots, taken in certain proportions "fromdifferent bales of a )lurality of bales from which bands 2 wrappingshave been removed, containing cotton oi dillerent vaoi rad is laid uponthe receiving apron or a hale-breaker und by the action oi? the lettermore or less mixed and loosened up. From the hale-breaker the cottonpasses through a short this to the adjoining opener, hv which the cottonis effectually opened up and torn apart, with the separation of dirt andthe coarser and other more easily removed impurities.

It happens with more or less frequency that a bale-band buckle, a nail,a stone, or some other hard object accidentally present in the baledcotton, passes forwurd to the opener from the bale-breaker or othermachine preceding the opener. The rotating cylinder of the openerrevolves at an exceedingly high rate of speed, and consequently thestriking of the teeth, blades, or heaters oi the said cylinder againstany such object contained. in the cotton entering the opener, producessparks, with the result mt cotton within the opener is ignited andconsumed. in some cases. also, the flame ex.- tending through the fluesystem through which the cotton passes from the opener to ed and thisapplication filed June 6,

bin or e distributing system, spreads the me so that loss results.

The ob ect oi? 1e invention is to provide again t the entrance, into onopener or the he, ot a heavy and hard object contained toe cottonpassing onward from a balebrealrer, or other machine feeding unopened oronly partially opened cotton or the like, through an intermediate fineto the said opener.

The present invention consists, essentially, n e mouthpiece inconnection with the said intermediate line, having an open lower endconsh ting a discharging mouth through which any heavy object such as abuckle? a nail, a stone, or the lilze,.will tall in droppino' themouth-piece, while the thro h h w into the mouthpiece will be carr edthrough horizontal, flue-portion into the opener ov a current or 9.11entering thro on uirdnlet in the hack of the deco, in line with suchhorizontal. flu portion, 4 i i 'io.=.sziti :-u illustrated in the draw-,n pliiwl in combination with a be e cooiiei'atingr with a verticalopener. l or the drawings shows in vertical oi the bale-breaker andverl'ogether with the mouth-piece ll line-portion intermediate the two'nioehines.

Fig. 2 is a rear elevation of the mouth piece.

Fig. .3 is a top view thereof. l in. sis a view thereof in vertioalsection on line 4-, 4-, o:t l.

The bale-breaher 1 and vertical opener 2 which ure partially shown inFig. 1 are of more or less conventional type. 12 is the mouth-piece intowhich the material operated upon is fed by the delivering devices of thelmle-breztln-xr, and 13 is the horizontal thieo iortion through. whichthe material passes from the lower port of the mouthpiece to theinterior ol? the Vertical. opener. "l; is the revolving so-ealledcylinder of the lo the perforated shell within which the said cylinderrotates, and 16 is the flue throu n which the opened material is carriedto a bin or a distributing system after leavino; the opener.

The c vlinder of a vertical opener is, as shown, conical in shape, itssmall end being helovr and its large end above. The

material to be subjected to the action of the said cylinder is suppliedto the small lower end of the cylinder, and as the cylinderrotates thematerial passes from such end upward within the opener toward the largeupper end of the cylinder, and from the top of the opener the materialis discharged. through the fiue 16.

The mouthpiece 12 extends down to the level of the small lower end ofthe cylinder, and the horizontal flue-portion 13, located at suchlevels, leads inward to such end.

At 0 is an air-inlet in the lower portion of the back-wall of themouth-piece, in line with the passage through the )horizontalflue-portion 13. The inward current of air through the said inlet andacross the lower portion ofthe mouth-piece, induced by the suctioncaused by the rotation of the cylinder, and by the tan constituting apart of the system, entering behind the fibrous material delivered. bythe bale-breaker into the mouth-piece and falling down between theair-inlet and such passage, operates to carry such material directlyinto and through the said passage.

In accordance with the invention, the, lower end of the mouth-piece 12below the air-inlet 0" is open, providing a discharging mouth a throughwhich any heavy object such as a buckle, a nail, a stone, or the like,will fall in dropping to the said lower end,

and thereby pass entirely out of the mouthpiece.

Ordinarily, the cotton fed into the mouthpiece bythe delivering devicesof the balebreaker will be carried into the passage or the horizontalflue-portion 13 by the current of airflowing through the air-inlet c andacross the lo-wer portion of the mouth-piece, and by such upfiow of airas takes place through the discharging mouth itself. Only exceptionallycompact and heavy tufts, etc, will pass out through the mouth a. Thesaid upflow through the discharging mouth will not interfere with thedropping of heavy objects like those named out through such mouth.

For the purpose of enabling the area of the air-inlet 0 to be varied atwill, to thereby regulate the rate of flow of the current of airentering at such air-inlet, and through the discharging mouth a, and theeffect 01'' the suction in carrying cotton into the horizontalflue-portion 13,1provide a damper for the air-inlet, by means of whichthe air-inlet may be closed or opened to any required extent, suchdamper consisting in this instance of a'slide a mounted in guides a aupon the back of the lower portion of the mouthpiece.

What is claimed asthe invention is,

1. In preparing machinery, the combination with an opener, a supply fineleading thereto, and means operating to supply fibrous material, of amouth-piece receiving the material from the said means, having at oneside anopening through which the material passes from the mouth-pieceinto the passage through said supply-flue and at the other an air-inletopposite the said opening, through which air enters behind fallingmaterial in line with the opening and also having at its lower end adischarging mouth through which heavy foreign objects drop from theinterior of the mouth-piece.

2. lnpreparing machinery, the comb-ination with an opener, a supply flueleading thereto, and means operating to supply fibrous material, of amouth-piece receiving the material from the means having at one side anopening through which the material passes from the mouthpiece into thepassage through said supply-flue and at the other an air-inlet oppositethe said opening, through which air enters behind material in line withthe opening, and having at its lower end a discharging mouth throughwhch heavy foreign objects drop from the interior of the mouth-piece,and an adjustable damper by which the rate of air-flow through saidair-i1ilet is regulated.

In testimony whereof I atiix my signature in presence 0'! two witnesses.
